DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a solar advertisement display device S of the present invention. A is an energy receiving plate, which is configured by arranging a plurality of solar cells 1 in an array type so that each light receiving surface 1a is exposed to the outside, and a frame 2 thereof
Both sides of the light receiving surface 1a are pivotally supported above the display device B so that the light receiving surface 1a can be adjusted in inclination according to the direction of the sun.

B is provided with a display portion 3a for advertisement in the center, and a plurality of light emitting lamps 4 ... Are provided around the display portion 3a.
The display device is provided with an arrow-shaped decorative frame display portion 3b in which (LEDs and incandescent lamps) are arranged and a special advertisement display surface 31 is formed as a whole. The plurality of light-emitting lamps 4 ... Arranged in the decorative frame display portion 3b are sequentially lit from the starting point of the arrow-shaped decorative frame display portion 3b toward the tip of the arrow in order to enhance the advertising effect. The light emitting lamps 4 ...
Looks like it's spinning around.

The solar type advertising light S of the present invention as described above is
It may be used as an outdoor signboard light, or may be installed indoors so that it can be used. Further, the solar advertisement display device S of the present invention as described above is used with the energy receiving plate A facing the sun, and the power generation output generated by each solar cell arranged on the energy receiving plate A will be described later. The power capacitor C, which is stored in the large-capacity power capacitor C and stores the electric charges in this way, is connected to the booster circuit 16 to connect the light emitting lamps 4 ... Connected via the lighting control circuit 17. It is possible to drive lighting or blinking with a lighting pattern prepared in advance.

As the large-capacity power capacitor C used here, an electric double-layer capacitor can be adopted, which has an order of magnitude larger capacity than the conventional large-capacity capacitor, and has a short charging time and is dependent on temperature. The impact is small,
It is lightweight, safe, and clean with no environmental pollution problems.

FIG. 2 shows the internal structure of the solar advertisement display device of the present invention. 1 is a solar cell provided on the energy receiving plate A side, 11 is an overvoltage prevention circuit that bypasses the power capacitor C when a voltage exceeding the withstand voltage is applied, and 12 is a charging voltage of the power capacitor C more than the voltage on the solar cell side. When the voltage drops, the backflow prevention diode that prevents the electric charge accumulated in the power capacitor C from flowing back to the power source side, and 13 is an overvoltage detection circuit. When an excessive voltage higher than the withstand voltage is applied to the power capacitor C. First, the overvoltage prevention circuit 11 is activated. Further, 16 is a booster circuit that raises the electric energy accumulated in the power capacitor C to a voltage level to be supplied to the light emitting lamps 4 of the display device B, and 17 is prepared in advance for the light emitting lamps 4 ... This is a lighting control circuit that drives lighting or blinking in a lighting pattern, and incorporates a constant current and constant current circuit that supplies a constant level of current and voltage according to the light emitting lamp 18 that is a load. SW and SW 'are switches.

Since the advertisement display device of the present invention is configured as described above, the power generation energy generated by the solar cell is accumulated in the large-capacity power capacitor C, and further boosted by the booster circuit to load the load. Since it is possible to supply current and voltage according to the above, it is not necessary to supply power from an external power source through an outlet as in the conventional device. FIG. 3 shows an external configuration of the present invention as set forth in claim 4, and in this embodiment, instead of the display device, a table-mounted display device that displays characters and images on the display screen 5. D has been adopted. In addition, 6 is a stand. In the case of such a display device D, it is usually installed in a store or the like, and a previously stored advertisement pattern is displayed on the display screen 5.

Since the basic structure is the same as that described above, a description thereof will be omitted, but a constant current circuit or a constant voltage circuit is applied to the lighting control circuit at any time, depending on the characteristics of the load.
